I have jeans like that from hollister. I’m really skinny and I fit a size 0 so I just get a size 1 instead. It’s not a big difference but the jeans are not super tight and they’re not really that loose either

Gap has a new limited edition style called slouchy skinny. I think they’re better in person than in the picture, fwiw.
I like skinny/straight leg jeans but my curves make me look like an inverted triangle with a sausage bottom in them. Then I found these, and I love them. They give the skinny/straight jean effect without being too tight. And they run a little big.
